ABSTRACT
Objective@#To compare the predictive validity of writhing movements assessments of neurological outcome between high-risk preterm and full-term infants.@*Methods@#High-risk preterm and full-term infants who accepted the general movements(GMs) assessments from July 2013 to April 2014 and took part in follow-up regularly for 1 year in the Newborn Pediatrics Department of the Fifth Central Hospital of Tianjin were confirmed as the participants.GMs recordings during writhing movements period (at least once) and fidgety movements period (at least once) were collected and assessed.Neurological outcome was confirmed by Peabody Developmental Motor Scale-2(PDMS-2) when the patients were 1 year old.Then the predictive validities of writhing movements assessments of neurological outcome between high-risk preterm and full-term infants were calculated and compared.@*Results@#There was no significant difference in the detection rate of writhing movements between preterm and full-term infant groups(χ2=1.592, P=0.207). There was no significant difference in the detection rate of fidgety movements between preterm and full-term infant groups(χ2=1.605, P=0.205). The sensitivity was 92.9%, the specificity was 90.0%, and the negative predictive value was 97.8% in the stage of writhing movement to the motor development outcome in preterm infant group; the sensitivity was 85.7%, the specificity was 94.0%, and the negative predictive value was 95.9% in the stage of fidgety movement to the motor development outcome in preterm infant group; there was a good consistency between the assessment of writhing movement and neurological outcome confirmed by PDMS-2(Kappa=0.703, P<0.01). The specificity was 71.0%, the positive predictive value was 55.6% in the stage of writhing movement to the motor development outcome in full-term infant group; there was a worse consistency between the assessment of writhing movement and neurological outcome confirmed by PDMS-2(Kappa=0.555, P<0.01). Both the sensitivity and the specificity were 75.0% in the stage of writhing movement to the cerebral palsy in preterm infant group; there was a poor consistency between the assessment of writhing movement and neurological outcome confirmed by PDMS-2(Kappa=0.311, P<0.05). The specificity was 85.4%, the positive predictive value was 22.2% in the stage of writhing movement to the cerebral palsy in full-term infant group; there was still a poor consistency between the assessment of writhing movement and neurological outcome confirmed by PDMS-2(Kappa=0.319, P<0.05). Both the sensitivity and the negative predictive value were 100.0% in the stage of fidgety movement to the cerebral palsy in both preterm and full-term infant groups.@*Conclusions@#The predictive validity of writhing movements assessments to the motor development outcome in preterm infant group is higher than in full-term infant group, and it can be used as a tool for early and accurate prediction of neural development outcome of brain injured premature infants.The predictive validity of writhing movements assessments of the cerebral palsy is poor.Both the sensitivity and the negative predictive value were high in the stage of fidgety movement to the cerebral palsy in both preterm and full-term infant groups, and it may be used to predict the cerebral palsy earlier.
